VACUUM CLEANER ATTACHMENT Application led October 24, 1928. Serial No.314,727.

The invention relates to attachments to be removably'fitted to theflexible tube of vacuum cleaning machinery, and provides a brush tippednozzle designed most especially for tufted upholstery to enable thecreases,

' folds and depressions to be reached.

The nozzle is formed with a attened end and curved tip in which isprovided the opening through which the dust laden air is drawn lo whenthe device is in action. Plates are adapted to be interchangeably fittedto the flattened sides of the nozzle and are provided With brushmaterial. The outer marginal edges of the plates are preferablychanneled for strength and reception of the bristles or other materialforming the brush.

The invention will be described more fully hereinafter, andcorresponding parts are referred to in the specification and designatedzo in the several views of the accompanying drawings by like referencecharacters.

In the drawings:

Figure 1 is a side View of a vacuum cleaner nozzle embodying theinvention a portion being broken away.

Figure 2 is a detail sectional View on the lin-e 2-2 of Figure 1 lookingin the direction indicated by the arrows.

Figure 3 is a transverse sectional view on the line 3 3 of.Figure 2.

The numeral '1 denotes the nozzle and 2 the usual flexible tube of avacuum cleaner. In accordance with the present invention the eX- tremityof the suction end of the nozzle is curved and formed with an opening 3.The receiving end of the nozzleis flat.,4 A plate 4 is tted against eachside of the flattened end and is coeXtensive therewith.

Screws 5 or like fastening means secure the 40 plates f1 to the sides ofthe flattened end of the nozzle. It is observed that the plates 4 may befitted to either side since one is the counterpart of the other. Theouter marginal portion of each of the plates 4 is pressed outwardly, asindicated at 6, to form a channel which reinforces the plates andprovides convenient means for the attachment of brush material 7 to theplates.

The brush material 7 may consist of brisci) tles which may be attachedto the plates in any manner practiced in the art. The arrangementresults in the provision of a brush which projects beyond the sidesandedges of the flattened end and worn brushes may be v readily replacedat a nominal cost. The attachment is designed chiefly for upholsteredfurniture, as it enables the creases, folds and crevices to be easilyreached for removal of the dust, lint and other accumulation.

Having thus described the invention, I claim:
